"After having a horrible experience with Andre and filing a complaint with the GM for the area, results still remain to be seen. So professionalism is non-existent and follow-thru still hasn't happened. The word of the GM, contractor supv as well as the actual contractors/engineers are garbage. Character by way of integrity and keeping their word is definitely not available with this company. Don't believe anything they say."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

Daniel started his construction career in 1983 as an apprentice in Switzerland, Europe. There he learned from experienced old school carpenters how to timber frame and build log houses. Cutting mortise and tenons for structural posts is still something that's done today. Since the late 80's, Daniel has learned all about the ever-changing U.S. construction industry. Daniel started his own remodeling company in 2001 and has since designed and built many additions and remodels in and around Montgomery County, MD. Due to years of experience, Daniel is able to make design changes that make construction easier and cheaper. He has proved himself to be a great communicator so that all parties involved in a remodeling project work as one. His ability to plan, schedule, and execute projects have made jobs less stressful and more rewarding for his clients. Things most frequently mentioned in client reviews are that Daniel and DK are staying within budget, getting the job done on time, are responsive and available, have clean and organized job sites, and are experienced.

FAQs for concrete injection leveling mudjacking projects in Kensington, MD

Mudjacking and foam jacking differ significantly in both materials and methods. Mudjacking uses a cement-based slurry to fill voids beneath a slab, while foam jacking uses expanding polyurethane foam delivered under high pressure to achieve superior structural support. This material distinction enhances load-bearing strength and overall stability in your repair.

Mudjacking takes between one and three days to dry completely. During this time, it's important to avoid putting weight on the slab until it's fully cured. The drying time depends on the project size and environmental conditions. In contrast, polyurethane foam used in foam jacking can cure in as little as one hour.

No, mudjacking is not a permanent fix for sinking concrete. While it effectively lifts the slab and can last five to 10 years, it doesn't address underlying soil issues that may cause future sinking. For a more permanent solution, you might consider foam jacking or complete slab replacement, which can address deeper structural problems.
